    Hi all, can anyone tell me who distributes this make of heater in Ireland? It came secondhand with a milking parlour, without instructions or installation directions. It is a "prisma plus" model 120 litres and the label says 6bar pressure. Can these be installed by a lay person? And are they fed from a header tank or direct from the mains? Some scary stories on here about dairy heaters, so all advice gratefull recieved.

    Having seen a lot of Dairy hot water installs i'v still yet to see a safe install, which is unfortunate as I feel cows have the right not to be blown up in a mist of super heated steam, but it could be handy for a mornings espresso.

    I don't know the make of heater you have but usually they are unvented which means they come with a long check list of very important safety requirements(especially as the temperture of the water is higher than a domestic install), if the safety requirements aren't met than you leave yourself at risk of things going Kabang.

    Fitting them to a pump is dependant on manufactures instructions as at times this can be a problem as the pump can switch off with the tank half filled causing the heater to cook.

    They tend not to like well water but that's dependant on the well/heater.

    Personally being a simple man I like floor standing direct unvented cylinder that have two adjustable immersions to achive the higher tempertures required and are easy to maintain, but costly to run

    I would advise getting a good plumber who understands UK:eek: G3 water regs(as that's what your judged on by a coroner/vet if things go bang), I wouldn't fit it without specific manufactures instructions and while I'm being miserable a secondhand heater would make me nervous, it's like nicking someone's pint, your never quite sure what it is or what they've done to it;)

    Hey, thanks, Gary71. The heater came with the rest of the parlour, but had been taken out of the dairy before I got to see the setup. Inventum seem to be Dutch, but mainly making coffee machines now. I will call a local Plumber who has a good rep, cause I don't want to be standing beside it if it goes BANG. I would be connecting to my own well, so that could cause problems, I suppose. Thanks for the response. Must look up the G3 regs. I had thought of sticking an immersion into a stainless steel barrel I have, but thought I would try and see if this thing works, first.

    G3 is water regs that come with a two day safety course that must be passed before a installer can fit a unvented cylinder the installation is then inspected by the local building inspector before it can be used, here we have nothing but if anything does go wrong it's the G3 regs that are used by insurance companies to determine fault.

    What ever you do bear in mind these things are only a problem if they become a problem and due to no inforcement you'll be left alone but the clipboard warriors that follow a problem will check whatever you do with a fine tooth comb.

    After all that you may find its not unvented:D

    Well Gary, just to let you know how things ended up. Hooked it up myself, and it both filled and heated perfectly. Joined to the well and used a lever valve to isolate the supply. However a few things occurred which were puzzling me. The supply pipe was becoming pressurised if the lever valve was left open, and sometimes no water at the outlet. So the plumber arrived today and in about 2 minutes realised that the supply and outlet pipes were reversed. This is a puzzler, as that's the way it came to me, with the outlet tap already attached, so lucky escape really. Probably a good job I had the thermostat set only for about 60 degrees .
